Distr. Supra muscos destructos (Grimmias) in latere 

 rupis in regione subalpina mentis livaara in Kuusamo (Vain., 

 f. subaromatica). 



Obs. 1. In f. subtabacina (Nyl.) Vain, sive in f. typica thallus 

 verrucis demum irregularibus, clavatis ramosisque ad instar thalli 

 Th. caeruleonigricantis, saepe etiam reniformi-sinuatis et raro hypo- 

 thallo fruticuloso brevi. Apothecia primum margins modice incrassato. 

 Conidia sec. Tli. Fr. „tenuissima, acicularia, leviter curvata, long. circ. 

 0.015 — 0.019 mm". „KHO partes obscurae fiunt magis rubricosae. Para- 

 physes laxe cohaerentes. Hymenium jodo leviter caerulescit, dein sub- 

 vinose rubet" (Th. Fr.). 



Obs. 2. F. subaromatica Vain. (Lecidea subaromatica Vain. Adj. 

 Lich. Lapp. II, 1883, p. 6). Verrucae thalli minus evolutae, simplices 

 aut ramosae, parum clavato-elongatae, hypothallo indistincto. — Apo- 

 thecia lat. 1 — 1.3 mm. Hymenium O.04o — O.oso mm crassum, totum dilute 

 fuscescens aut epithecio pauUo intensius fuscescente. Paraphyses 

 arete cohaerentes. Hypothecium crassum, fuscescens vel rubrico- 

 sum. Sporae oblongae aut ovoideae, simplices aut 1-septatae, long. 

 0.011 — 0.018, crass. O.0045— O.ooe mm. Hymenium jodo persistenter cae- 

 rulescens. 



Obs. 3. Lecidea tabacina Nyl., Lich. Paris (1896) p. 87, sporis 

 ellipsoideis vel ellipsoideo-oblongis, simplicibus, long. O.oio — O.ois, crass.

 „Psora tabacina Ram. in D.C. Fl. Fr. II (1794) p. 367 sec. herb. D.C. 

 omnino sit Lecidea silacea Ach.", ut ait Th. Fr. 1. c.
